PhD Studentship: In-process measurement and control for metal laser machining

University of Nottingham

Location: University of Nottingham

A fully-funded 4 year-PhD studentship starting in September/October 2018 is available in the Doctoral training centre for Innovative Metal Processing (IMPaCT) at the University of Nottingham.


Laser machining has huge potential in a wide variety of fields due to its tool free manufacturing capabilities and processing speed compared to traditional metal cutting. There is a strong drive to adopt laser techniques in industries such as medical and aerospace due to these sectors requiring high levels of confidence in the structural quality of their parts. Current methods for testing laser machining parameters and component quality rely on post process analysis of the manufactured parts through both destructive and non-destructive methods, which is costly and time consuming.

This project aims to improve the reliability of laser machining processes by integrating topography measuring technology into the laser chamber. The first part of the project will be to quantitatively assess the important defects and topography features that need to be detected using off-line technologies (optical and electron). Once a catalogue of features has been produced, the measurement system will be designed with speed being the defining characteristic. Sensors to be investigated include fringe projection, photogrammetry, focus variation and laser scattering, and potentially combinations of these. The sensors themselves are already under development at Nottingham, so the project will focus on their integration and use to control the laser manufacturing process.

Funding Information:

IMPaCT students are fully funded studentships which include:

  • A full UK/EU fee waiver for 4 years
  • An annual tax free stipend of £14,777 (2018/19)
  • Possibility of additional top up for industry sponsored projects.
  • Generous Research Training Support Grant.

Studentships are open to UK Home / EU applicants who meet the residency criteria which is set out by the Research Council EPSRC.

A limited amount of partial funding is available for exceptional international applicants who are highly qualified and motivated.  Due to the nature of this funding, the CDT would only be able to cover the cost of the Home/EU fees and therefore the applicant would need to either find alternative funding or self-fund the fee difference
